Impressive, wow, who would of thunk there are virtual airshows? It almost makes me want to do some flight-simming but like other people commenting here I suck and generally end up stuck on the ground or landing into the ground forgetting about things like flaps, wheels, speed etc.

How do they film this and package it into something the general public can watch?

That’s a nifty idea. I wonder what the future could hold for virtual performance. If the simulation requires the same skills needed to fly the real aircraft, then I don’t see why this couldn’t eventually become more prominent, mostly for reasons of practicality.
While viewing an air show in person is no doubt a more breathtaking experience, they are a really expensive way to entertain people. Then there’s all the pollution caused by the jet fuel, smoke trails and pyrotechnics. There’s a large international airshow near where I live, and every year the whole valley is choked with smog from the event.

Whether we like it or not, humans are going to have to start finding more sustainable pastimes like this VFAT event.
